FM18W08-SG Product Details

Functional Description 

The FM18W08 is a 32 K × 8 nonvolatile memory that reads and writes similar to a standard SRAM. A ferroelectric random access memory or F-RAM is nonvolatile, which means that data is retained after power is removed. It provides data retention for over 151 years while eliminating the reliability concerns, functional disadvantages, and system design complexities of battery-backed SRAM (BBSRAM). Fast write timing and high write endurance make the F-RAM superior to other types of memory. The FM18W08 operation is similar to that of other RAM devices and therefore, it can be used as a drop-in replacement for a standard SRAM in a system. Minimum read and write cycle times are equal. The F-RAM memory is nonvolatile due to its unique ferroelectric memory process. These features make the FM18W08 ideal for nonvolatile memory applications requiring frequent or rapid writes. The device is available in a 28-pin SOIC surface mount package. Device specifications are guaranteed over the industrial temperature range –40 °C to +85 °C.
